Ignore ACPI netlink events for GPEs which are configured as direct
GPEs. Such GPEs are forwarded to the guest directly as physical GPEs
using eventfd based forwarding of physical SCI interrupts (which
ensures that the GPE handling in the guest is synchronized with SCI
interrupt context in the host).
Forwarding via netlink should be used for emulated GPEs only.
With this change, we are still propagating all GPE events received by
the host to the guest. In the future we may need to enhance this logic,
since for some types of GPEs we may not want to inject them to the
guest at all, e.g. for Thunderbolt hotplug GPE we want to receive it
in crosvm and then inject a normal PCI hotplug interrupt instead.

In order to allow handling physical GPE in the guest, implement GPE
status & enable register bits read/write passthrough to/from physical
registers for selected GPEs (while for the rest of GPEs the registers
remain purely emulated).
We use Linux kernel's ACPI sysfs interface for accessing physical
GPE regs. Note that in particular for enabling/disabling GPEs we use
"mask"/"unmask" interfaces instead of "enable"/"disable", since we
want to do raw enable/disable, bypassing ACPICA's reference counting.
We only do "enable" when it is enabled for the first time, to ensure
that the ref count for the given GPE is > 0.
This of course assumes that the given GPE is enabled/disabled
exclusively by the guest, never by the host.
Thanks to Peter Fang for the idea to use mask/unmask.

In order to allow handling physical GPE in the guest, implement
physical SCI interrupts forwarding from the host to the guest.
It uses an eventfd based mechanism similar to how we normaly do
forwarding of other level-triggered interrupts. The difference is that
SCI trigger events from kernel are not injected directly to irqchip.
In order to support injecting both physical and virtual SCI interrupts
(so that some GPEs can be handled as physical while other GPEs can be
emulated), SCI trigger event is intercepted by ACPIPMResource which
injects it to irqchip via another eventfd - the same eventfd which is
used for injecting virtual SCI interrupts.
Similarly, resample event for physical forwarded SCI is received
via the same eventfd as for virtual SCI, then forwarded back to kernel.

Linux expects that PCI bars lie within a compatible bridge window, which

This change is required to remove pci=nocrs from the CrOS guest's kernel

In order to avoid deadlocks (when a Vcpu thread has locked the ioapic and
the ioapic sends a AddMsiRoute signal to the main thread which itself may
be busy trying to call service_irq) KvmSplitIrqChip defers IRQs by using
vector of delayed IRQs and queuing it up for the next main thread loop
spin.
The problem is that next loop spin will ever happen if there will be
any *unrelated* trigger event to be serviced which means IRQ reinjection
may take really long time, at least longer than some devices may assume
before timeout.
Instead of relaying on non-deterministic mechanism, make sure the next
trigger event for main thread is around the corner by:
- adding a new event - strictly related to processing delayed IRQs
- adding a new token type in main thread and correlate the new event
occurrence with process_delayed_irq_events() irqchip call
- writing to the new event as soon as new IRQ is added to the delayed
vector
This makes sure that delayed IRQs (if present) are always on main loop's
TODO list.
BUG=b:184871003
TEST=boot guest using crosvm --split-irqchip flag and check if IOAPIC
related IRQs are working

Stop using Tube::try_clone() as we want to remove this method.
This requires a change in how the GPU device tube is set. Cloning the
control tube on the VMM side allowed us to pass only one tube to the GPU
device, which received the first message asking for BAR information and
then immediately recycled its tube to send VmMemoryRequests.
Without cloning, we to create two full Tubes and pass the VmMemory tube
as part of the first message to the device. This is a bit more involved
but also safer.
BUG=b:222379833
BUG=b:221484449
TEST=`cargo run device gpu` replies to the initial message and receives
the tube from the VMM process.
